My university project group is currently designing (and hopefully realizing!) a self-cleaning fish tank. Please spare two minutes to take the following survey, which will give us vital information for deciding the specification of the new invention. My deepest thank you!

I have encounter a problem in your survey, there was a question "How often do you perform a complete clean-up (removing gravel from fish tank)?" The problem with this question is that a "never" option was not given. Because unless you are taking your aquarium apart to change layout you do not remove your gravel._________________Don't cry because your Sun is gone.

I also completed the survey. I thought what do you own/would be intersted in should be 2 different topics.

I would be interested in owning a HUGH tank, but a 280L is about the largest I've owned._________________"... instead of considering what to say when they write, people now just let thoughts drool out onto the screen,"
